Description

Technical Field

[0001] The present invention belongs to the technical field of electronic cigarettes, and particularly relates to a method, a system and related devices for regulating the output voltage of an electronic cigarette. Background Art

[0002] The existing output voltage modes of electronic cigarettes include the following three different modes: constant voltage output, constant power output and constant effective value output.

[0003] Constant voltage output means driving a load resistor with a constant voltage value. The disadvantage of this mode is that when the battery voltage is low, the output voltage decreases with the decrease of the battery voltage. At the same time, during the temperature change process of the heating wire, the resistance value changes, resulting in a large range of changes in the output power, and further affecting the taste of the generated smoke.

[0004] Constant power output is to simultaneously detect the current I flowing through the output resistor and the voltage value U applied to the load resistance value, and calculate the output power through the following power calculation formula:

[0005] P = D×U×I;

[0006] Constant power output means that under the regulation of the control unit, the PWM (Pulse Width Modulation) voltage value of the heating resistor changes synchronously with the resistance value of the heating resistor to maintain the same power, so that the atomization amount generated by the heating resistor heating the e-liquid is the same.

[0007] Constant effective value is based on constant power, and uses the square relationship to make the output power more stable, mainly using the following calculation formula:

[0008]

[0009] In the above formula, D represents the duty cycle of the PWM wave.

[0010] However, it is very difficult to detect the e-liquid amount in the cartridge. At present, there is no good solution to accurately detect the remaining e-liquid amount in the cartridge. Generally, to achieve the detection of the cartridge remaining amount, structures such as light reflection or refraction and liquid level sensors can be used. However, if the above detection structures are added, the manufacturing cost of the cartridge of the electronic cigarette will increase, which is not a good method from the perspective of production and manufacturing. Summary of the Invention

[0011] Embodiments of the present invention provide a method, a system and related devices for regulating the output voltage of an electronic cigarette, aiming to solve the problem that the existing electronic cigarette needs an additional detection structure to calculate the temperature of the heating unit and the remaining e-liquid amount of the smoke unit.

[0012] In a first aspect, an embodiment of the present invention provides a method for adjusting the output voltage of an electronic cigarette. The electronic cigarette includes a smoke unit and a heating unit for heating the smoke unit. The method includes the following steps:

The first preset power, the second preset power, and the third preset power respectively correspond to a first preset voltage, a second preset voltage, and a third preset voltage;

[0023] The preset rule is:

[0024] Furthermore, in step S4, the following sub-steps are included:

[0025] S41. Define the working duration of each time of the electronic cigarette as Ti, and the total working duration as T. Then the total working duration T satisfies the following relational expression (1):

[0026]

[0027] S42. Whenever the total working duration T accumulatively increases by a preset working duration, increase the heating voltage by a preset voltage increment.

[0028] Further, after step S42, the method further includes the steps of:

[0029] S43. Define the margin of the smoke unit as L, and the margin L satisfies the following relational expression (2):

[0030] L = L 0 -α×T (2);

[0031] In relational expression (2), L 0 is the value after the initialization of the smoke unit, α is a preset total working duration coefficient, and α is positively correlated with the average power of the electronic cigarette;

[0032] If the margin L is less than the preset minimum margin threshold L MIN , then stop the heating unit from working.

[0033] Further, after step S43, the method further includes the steps of:

[0034] S44. Define the heating temperature output by the heating unit as T emp , and the heating temperature T emp satisfies the following relational expression (3):

[0035] T emp = A×t 0 + K×(T - t 0 ) (3)

[0036] In relational expression (3), t 0 is the initial working time of the heating unit, A is a preset temperature change coefficient, and K is the heating coefficient of the heating unit;

[0037] If the heating temperature T emp accumulatively increases by a preset temperature increment, then increase the heating voltage by a preset voltage increment.

[0038] Further, after step S43, the method further includes the steps of:

[0039] S44. Define the heating temperature output by the heating unit as T emp , and the heating temperature T emp satisfies the following relational expression (3):

[0054] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0055] Please refer to Figure 1 , Figure 1 It is a flowchart of a method for adjusting the output voltage of an electronic cigarette provided by an embodiment of the present invention, and the method includes the following steps:

[0056] S1. Zeroize the time for the heating unit to heat the smoke unit, and use the current remaining amount of the e-liquid in the smoke unit as the initial remaining amount.

[0057] Specifically, the method provided by the embodiment of the present invention is used for an electronic cigarette including a smoke unit and a heating unit for heating the smoke unit. Step S1 is an initialization method for an electronic cigarette. The initialization of the electronic cigarette is to unify the parameters required in the following embodiments of the present invention. For existing electronic cigarettes, they are divided into disposable electronic cigarettes and refillable cartridge electronic cigarettes. The cartridge is equivalent to the smoke unit in the embodiment of the present invention, and the e-liquid that can generate smoke after heating is stored inside. The methods for initializing the above two types of electronic cigarettes in the embodiment of the present invention are different, but the purpose is to zeroize the heating time and obtain the remaining amount of the smoke unit in the electronic cigarette.

[0058] Exemplarily, for a disposable electronic cigarette, during the assembly process, there is a phenomenon that it is easily accidentally triggered, resulting in the smoke unit being heated and burned. This problem cannot be avoided whether through algorithms or load resistance detection, because the triggering mechanism needs to perform internal feedback detection in the normal working mode of the chip, and the heating unit will still be started for dry burning; the method for initializing a disposable electronic cigarette product can be to disconnect the battery from the electronic circuit through a switch or a plastic insert after all components are detected and assembled, to avoid the heating unit being accidentally triggered for dry burning when no e-liquid is injected;

[0059] For e-cigarette products with replaceable cartridges, initialization can be performed through the following three solutions: First, a button is used for resetting, that is, after each new cartridge is replaced, the reset switch is manually pressed to zeroize the heating time of the smoke unit; Second, the cartridge is quickly inserted and removed multiple times within a certain period for reset operation to initialize the entire e-cigarette system; Third, electronic tag recognition. This method mainly reads the electronic tag code inside the cartridge and compares it with the previous cartridge code. If they are inconsistent, the system is initialized; if they are consistent, the previous heating and remaining data are retained.

[0060] S2. Output a heating voltage through the heating unit to make the heating unit heat the smoke unit.

[0061] Further, before step S2, the following steps are also included:

[0062] Judge whether the e-cigarette is in a smoking state, where:

[0063] If so, make the heating unit output the heating voltage;

[0064] If not, make the heating unit stop working.

[0065] In the embodiment of the present invention, exemplarily, the method for judging whether the e-cigarette is in a smoking state can be to detect the airflow change value through an airflow sensor, and judge whether it is in a smoking state according to whether the airflow sensor senses an airflow change similar to a smoking action.

[0066] S3. Calculate the heating power according to the heating voltage, compare the heating power with a preset power, and feedback-adjust the heating voltage according to the comparison result according to a preset rule.

[0067] Further, in step S3:

[0068] The preset power at least includes a first preset power, a second preset power, and a third preset power that increase in sequence. The first preset power, the second preset power, and the third preset power respectively correspond to a first preset voltage, a second preset voltage, and a third preset voltage;

[0069] The preset rule is:

[0070] If the heating power is less than the first preset power, keep the heating voltage unchanged;

[0071] If the heating power is equal to or greater than the first preset power and less than the second preset power, set the heating voltage to be equal to the first preset voltage;

[0072] If the heating power is equal to or greater than the second preset power and less than the third preset power, set the heating voltage equal to the second preset voltage;

[0073] If the heating power is equal to the third preset power, set the heating voltage equal to the third preset voltage.

[0074] It should be noted that the embodiments of the present invention design three levels of increasing preset power. In actual applications, more levels of the preset power can be designed as needed to achieve the effect of gradually increasing the output power of the electronic cigarette and smoothly transitioning the taste over time.

[0075] S4. Obtain the total working duration of the electronic cigarette, and linearly adjust the heating voltage according to the total working duration.

[0076] Furthermore, in step S4, the following sub-steps are included:

[0077] S41. Define the working duration of each time of the electronic cigarette as Ti, and the total working duration as T. Then the total working duration T satisfies the following relational expression (1):

[0078]

[0079] S42. Whenever the total working duration T accumulatively increases by a preset working duration, increase the heating voltage by a preset voltage increment.

[0080] The preset working duration can be set according to the actual situation. Exemplarily, the heating voltage has a linear relationship with the total working duration T, that is, when the electronic cigarette is working continuously, as the total working duration T increases, the heating voltage slowly increases.

[0081] Generally, when the heating voltage increases, the actual working power of the smoke unit will also increase to a certain extent, thereby increasing the release amount of the smoke. There are two advantages to dynamically increasing the output power in this way: First, generally, after an electronic cigarette is smoked to a certain extent, due to the reduction of the stored e-liquid amount in the smoke unit, the atomization amount of the e-liquid generated per unit time will also decrease accordingly. To achieve the same user experience, the output power is increased to maintain the smoke output per unit time. Second, in electronic cigarettes with either cotton cores or ceramic cores as the smoke units, as the usage time increases, oxides will be generated on the surfaces of the heating unit and the smoke unit due to chemical reactions and adhere to the place where the heating wire of the electronic cigarette contacts the e-liquid, resulting in a decrease in the atomization amount of the e-liquid at the same power. Therefore, increasing the output power can make the user experience more consistent.

[0082] Furthermore, after step S42, the following step is also included:

[0083] S43. Define the margin of the smoke unit as L, then the margin L satisfies the following relational expression (2):

[0084] L = L 0 -α×T (2);

[0085] In relational expression (2), L 0 is the value after the smoke unit is initialized, α is a preset total working duration coefficient, and α is positively correlated with the average power of the electronic cigarette;

[0086] If the margin L is less than the preset minimum margin threshold L MIN , then stop the heating unit from working.

[0087] The main influencing factor of α is the average power of the equivalent output, that is, the greater the power, the greater the consumption of the e-liquid in the smoke unit, and the smaller the power, the smaller the consumption of the e-liquid. Due to the protection mechanism and system error, a certain margin is reserved for the calculation of the e-liquid volume, that is, the minimum margin threshold. When L decreases to be lower than L MIN , stop the heating unit from working, and at the same time turn off all functions of normal smoking, so as to prevent the smoke unit from being dry-burned and causing potential safety hazards.

[0088] Furthermore, after step S43, it further includes the step of:

[0089] S44. Define the heating temperature output by the heating unit as T emp , the heating temperature T emp satisfies the following relational expression (3):

[0090] T emp = A×t 0 + K×(T - t 0 ) (3)

[0091] In relational expression (3), t 0 is the initial working time of the heating unit, A is a preset temperature change coefficient, and K is the heating coefficient of the heating unit;

[0092] If the heating temperature T emp accumulatively increases by a preset temperature increment, increase the heating voltage by a preset voltage increment.

[0093] Specifically, K is determined by the material of the heating unit and its resistivity.

[0094] The present invention also provides another embodiment. For step S44, it can also be:

[0095] Define the heating temperature output by the heating unit as Temp , the heating temperature T emp satisfies the following relational expression (3):

[0096] T emp = A × t 0 + K × (T - t 0 ) (3)

[0097] In relational expression (3), t 0 is the initial working time of the heating unit, A is a preset temperature change coefficient, and K is the heating coefficient of the heating unit;

[0098] If the heating temperature T emp accumulatively increases by a preset temperature increment, the heating voltage is reduced by one preset voltage increment.

[0099] In this embodiment, as the heating temperature gradually increases, the heating voltage gradually decreases. Such a setting is considered because the material constituting the heating unit may have different temperature heating coefficients. Compared with another embodiment, if the heating voltage increases when the temperature increases, the material of the corresponding heating unit has a positive temperature coefficient characteristic; if the heating voltage decreases when the temperature increases, the material of the corresponding heating unit has a negative temperature coefficient characteristic.

[0100] The beneficial effects achieved by the present invention are that, since the voltage output and heating element that must exist in the electronic cigarette are used as data sources, the temperature of the heating unit and the remaining oil amount of the smoke unit can be calculated through an algorithm, and further the technical effects of preventing dry burning and automatically adjusting the output voltage to achieve a progressive change in power can be realized. On the premise of realizing the above functions, the manufacturing cost is saved.

[0101] The embodiment of the present invention further provides a system for adjusting the output voltage of an electronic cigarette. Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of a system 200 for adjusting the output voltage of an electronic cigarette provided by the embodiment of the present invention.

The computer device 300 includes: a memory 302, a processor 301, and a computer program stored on the memory 302 and executable on the processor 301.

[0127] S42. Whenever the total working duration T accumulatively increases by a preset unit working duration, increase the heating voltage by a preset voltage increment.

[0128] Furthermore, after step S42, it further includes a step:

[0129] S43. Define the remaining amount of the smoke unit as L. Then the remaining amount L satisfies the following relational expression (2):

[0131] In relational expression (2), L 0 is the value after the initialization of the smoke unit, α is a preset total working duration coefficient, and α is positively correlated with the average power of the electronic cigarette;

[0132] If the remaining amount L is less than a preset minimum remaining amount threshold L MIN , then stop the heating unit from working.
